See pic below Tony. Looks like the filtered oil lubricates the governor drive gear before draining into the sump. On the CMP it's plumbed directly into the sump.
Something to be aware of with bypass filtration is that there needs to some restriction of flow, otherwise all the oil will go through the filter and none through the motor, esp. if there's no cartridge fitted. Presumably there's a restrictor in the filter inlet, ie. on the side of the filter housing. I'm not familiar with the fittings myself but it's something to confirm before assembly. Hopefully someone here can advise.
The two plugged passages are interesting, they could just be access holes for machining, or perhaps they're for flushing the system. I really don't have a clue to be honest.
Re crankshaft, it's only the rear main bearing that's fed directly from the oil pump, and from there to No.4 crankpin through a diagonal passage in the crankshaft itself. The rest of the crankshaft is fed from the main oil passage which runs along the top of the camshaft. There's a good diagram in Section C. Lubrication in the manual, the only difference being the full flow configuration.
